WHAT IS F.O.G? Fats, Oils, and Grease (F.O.G) come from animal or vegetable base foods used for cooking. Examples include lard, oils, butter, shortening, salad dressing, margarine, sauces, and dairy products.
WHY IS F.O.G A PROBLEM?
When F.O.G. enters the sewer system, it congeals, restricting the flow of wastewater. When the system is clogged as a result of F.O.G, raw sewage can back up into sinks, toilets, basements and can overflow into Casco Bay and other local waterways.
WHY DOES PORTLAND HAVE A F.O.G. PROGRAM? 1. MANDATORY
The City of Portland is required by federal law to reduce overflows to Casco Bay and other waterways. Implementing a program that keeps the sewer system free of F.O.G. helps to reduce these overflows. 2. COSTS
Increasing costs for maintenance of sewer system and pump stations in an effort to keep them functioning. The City cleans 28,000 feet of sewer twice per year at $7.60 per linear foot for grease removal. In addition, there are 8 pump stations cleaned quarterly that remove an upwards of 50 tons of grease annually at $110 per ton. Capturing F.O.G. at the source can help limit rising costs. 3. CAPACITY
When F.O.G enters the sewer system, it congeals, restricting the flow of wastewater through the lines. This is similar to a blockage in a human artery. If the sewer line become restricted, it can result in sewage back ups in your home or business and can overflow into Casco Bay or other local waterways.
